Tradescantia Trial Site Overview
The site chosen is an irregular area approx 50-80m long by 30-40m deep from the Kaipatiki roadside margin of 1999 planting, down to the stream and up the opposite bank as far as the Native Plant Trail along the bottom of a steep bank below housing.
On this side of the stream there is little Tradescantia beyond, ie uphill of, the Native Plant Trail, which is bordered by very steep banks dominated by kanuka and ponga, topped by housing and with only partial tree canopy, including many large pines, wattles, and Elaeagnus. Pine and ponga litter are probably suppressing both native and weed germination.
[Large manuka and mahoe have been observed over the years knocked down by pine-falls. A mature Towai, along with native understorey, was knocked down here in a wattle-fall in 1997. No other Towai have yet been observed, but a seedling has now been found much further upstream].
The Tradescantia Trial Site’s length length is from the signposted entrance to the Reserve opposite the Glenfield College tennis courts, downstream to a steep bank with few trees between the planting and the wild revegetation along the streamside.
